REGISTERING OR INDICATING DEVICE FOR TURNSTILES.

Specification of Letters Patent.

Eatented Jan. 9, 1906.

Application filed March 11, 1905- Serial No. 9,635.

To all whom it nuty concern:

.Be it known that I, ALBERT MARSH, theatrical manager, a subject of the King of Great Britain, residing at 150 Oxford street, London, England, have invented certain new and useful Improved Means Applicable for Use in Registering or Indicating Admissions by Turnstiles or the Like, of which the following is a specification. I

This invention relates to improved means applicable for use in registering or indicating admissions by turnstiles or the like, the objects being to prevent the possibility of a double contact being effected, to secure the apparatus against fraudulent movement, and to enable the apparatus to be employed in a duple capacityviz., for entering and leaving public places or inclosures, indication being effected on the admission but not on the exit.

In the specification to a previous patent, No. 735,379, dated August 4, 1903, I described a machine for registering or indicating at a distance admissions by turnstiles; but it has been found in practice that such machine, while giving fairly-satisfactory results, is capable of being manipulated so as to set up a double contact by the reversal of the gate.

It is the purpose of the present invention to obviate or to minimize the aforesaid defeet, and to this end I have devised the construction hereinafter described with reference to the accompanying drawings and defined by the claims hereto.

Figure 1 of the drawings represents a plan of the device having my present improve ments applied thereto, the cover of the box or holder being removed to expose the mechanism contained therein. Fig. 2 is a vertical section showing the aforesaid device fitted in the box or pocket in the top pertaining to the turnstile and showing its connection with the shaft or spindle of the turnstile. Fig. 3 is an enlarged view in plan of the contact-maker and means for holding same from back movement. Fig. 4 is a plan of the upper extremity of the shaft or spindle pertaining to the turnstile.

According to my invention the contact is formed as a disk a, having radial arms a, provided with pivotallymounted blade a controlled by springs, such as a so as to afford a yielding contact with the double-contact piece I; 1), whereby circuit is established through the wires 1) b, a battery or other electricitygenerating apparatus, and the in- (licator or registering device, such as described in the specification of my aforesaid previous patent. The disk a is mounted freely on the spindle c and situated between two bosses d (1, the said bosses being secured by any suitable means to the spindle 0, so as to be rotated thereby. Upon the upper face of the disk a teeth a are formed, and pivoterably arranged so as to normally engage the teeth a by its weight, although, if found requisite, a spring may be applied thereto for insuring contact with the upper face of the disk a and the teeth (L The upper extremity of the spindle 0 takes a bearing in the cover-plate c of the box or holder 6 and the lower end in the base-plate c the said spindle passing through the latter plate and being furnished with a key or pin 0'. The upper extremity of the shaft or spindlef of the turnstile is suitably recessed for the reception of the spindle c and key or'pin c, as shown at f X in Fig. 4. The said upper extremity may also be provided, if required, with the usual ratchet f and pawl arrangement for preventing the reverse movement of the turnstile; but if the apparatus be required to serve for entering and leaving the ratchet and pawl may be dispensed with.

g is a spring keeper or arrester furnished with a stop g,- preferably formed as an inclined surface having an abrupt termination 9 whereby the contact or circuit is maintained, the said keeper or arrester also enabling the contact-maker to break away from and clear the contact after establishing the circuit.

Upon the turnstile being rotated in the direction of the arrow 7L, Fig. 1, by the passage of a person therethrough the spindle c is rotated through an angle of ninety degrees, with the result that the boss d rotates to a corresponding extent and by means of the pawl d carries the disk a and contacts a around, the contact a next in position or situated in {proximity to the contact-piece l) 6 making contact with the latter and effecting a registration or indication, as will be clearly understood. It will be seen that the yielding contact in advance of the contact a for the time being against the contact-piece b b will be engaged by the stop 9 g on the spring keeper or arrester g and the contact held against a back or return movement, a double contact being thereby prevented. Thus ally mounted on the boss (1 is a pawl (Z prefthe contact once made must be completed, as no back movement of the contact-maker is possible, owing to the disk being held by the abrupt termination g of the stop g. The turnstile may, however, be rotated in the reverse direction by reason of the pawl (Z riding freely over the teeth (L The counting mechanism I prefer to employ is that described in my aforesaid previ ous specification, which is similar to the apparatus described in the specification of my United States Patent No. 693,414, of 1902.

What I claim, and desire to secure by Let ters Patent of the United States, is

1. In a registering or indicating turnstile, the combination of hinged spring contactarms, a disk carrying said arms, a spindle passing through said disk, bosses on said spindle situated above and below the disk, means for clutching the disk so as to be operated by said spindle in one direction of rotation and a keeper or arrester for the contactarms.

2. In a registering or indicating turnstile, the combination with the turnstile-sha'ft of a spindle having a cross-pin or key therein a disk freely mounted on said spindles radial hinged spring contactarms on said disk a boss above and a boss below the said disk, a pawl on the upper boss and teeth on the upper face of the disk for said pawl to engage, a keeper or arrester and a stop on said keeper.

3. In a registering or indicating turnstile, the combination of hinged spring contact arms a disk carrying said arms a spindle passing through said disk, bosses on said spindle situated above and below the disk, means for clutching the disk so as to be operated by said spindle in one direction of rotation, and a contact-piece for establishing electrical connection with an electricity-generator and indicator.

4. In a registering or indicating turnstile, the combination of hinged spring contactarms a disk carrying said arms a spindle passing through said disk, bosses on said spindle situated above and below the disk, means for clutching the disk so as to be operated by said spindle in one direction of rotation, a spring keeper or arrester and a stop on said spring-keeper.

5. In a registering or indicating turnstile, the combination of hinged spring contactarms a disk carrying said arms a spindle pass ing through said disk, bosses on said spindle situated above and below the disk, means for clutching the disk so as to be operated by said spindle in. one direction of rotation and a keeper or arrester for the contact-arms, and a contact-piece for establishing electrical connection with an electricity-generator and indicator.

6. In a registering or indicating turnstile, the combination with the turnstile-shaft 01'' a spindle having a cross-pin or key therein a disk freely mounted on said spindle radial hinged spring contact-arms on said disk a boss above and a boss below the said disk, a pawl on the upper boss and teeth on the upper face of the disk for said pawl to engage, a keeper and arrester and. a stop on said keeper, a contact-piece for establishing electrical connection with an electricity-generator and indicator.

7. In a registering or indicating turnstile, the combination of hinged spring contact arms a disk carrying said arms a spindle passing through said disk, bosses on said spindle situated above and below the disk, means for clutching the disk so as to be operated by said spindle in one direction of rotation, a spring keeper or arrester and a stop on said springkeeper, a contact-piece for establishing electrical connection with an electricitygenerator and indicator.

In testimony whereof I have hereunto set my hand, in presence of two subscribing witnesses, this 28th day o'l February, 1905.
